Konica Minolta Printer Manager and Tray Icon
I have a Konica Minolta 2300W color printer directly attached to my computer via parallel port. The desktop has a Konica printer manager that watches the toner levels and you'd use this utility to rotate the toners to swap them out respectively. Well one of the toner cartridges started running empty and so the printer management utility started graphically highlighting the near-empty toner cartridge in red. It was right around this time when the toner was running out that I started noticing "MSTMON_P.EXE has encountered a problem and needs to close. We are sorry for the inconvenience." mes

Best practices for resolving mstmon_p issues

A clean and tidy computer is the key requirement for avoiding problems with mstmon_p. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the mstmon_p.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
